Should I but Galaxy S6?

I am looking for a good phone,I mostly use for fb.insta.SC.sometimes music and texting.If i use all these apps continuously,how many hours will battery remain from 100%? I have read so many reviews some say that this phone has so many bugs and some declare it the best phone of 2015! help me out please.Dont wanna take risk and then regret.thanks

The hours it will last depends on how much you use it so it will vary. As for the phone, the S6 is a really nice phone. I've never had any issues with it. The camera is one of the best out there right now and the build quality is very nice.
I think people that had any issues were the ones installing too many apps running at the same time.
If you are with a national carrier, see that their return policy is and try it out for your self.

so nice of you for replying.
how long uve been using GS6? and which color is best?
have you updated to Android Marshmallow?
sorry for asking so many qs at a time.

I bought the S6 at launch back in April/May. Color is subjective to your personal preference. I got a black one but I'll probably get a white phone next time. I like to go back and forth between black and white.
No Marshmallow yet as I have AT&T and they are slow to update.
